Colle System: Pterodactyl Variation

About this opening

The Pterodactyl variation arises from a Colle System move order where Black adopts a hypermodern setup: a g7 fianchetto, ...c5 and the ...Qa5+ check to hamper White's development and pressure the long diagonal. The play is asymmetrical and combative, Black seeking counterplay rather than symmetry. It is an original line, with an evocative name, for fans of atypical positions.
